  Audio Output to Beta Sp

  Posted by Xtothed on February 10, 2006 at 5:45 pm

  Hi all,

  I have two queries…that in some ways are related.

  I have edited and dumped down a TV commerical onto Beta SP, PAL 16:9 – via Final Cut Pro, Blackmagic Decklink and into the UWP 1800.

  My audio levels in FCP are set to – 18db. That is for the bars and tone, as well as the commercial peaking at just over this level as well. I then set this level upto 4 on my PPMs and into the Beta Recorder. It does look a low on the Beta’s levels and I have had complaints about the level being low on the tape. Am I doing all of this correctly? How can I assure that the -18db in Final Cut is -18bd on the tape.

  Secondly – the tech report – I have a tech reports with aspect ratio, programme codes, audio levels etc. – which I fill out accordingly. But I obviously I am not sure that what I am putting, in regard the audio especially, is correct. On top of this, in order for the commercial to be broadcast, I transfer the Beta SP to Digi Beta with another company. They are acting as the quality control at the moment (with regards the sound) but obviously I want to make sure I am giving them the right information and content on the tape.

  Hope someone can help – I will also post this in the Broadcast Video and FCP forums.

  Thank you.

  Xavier

  Tone on Beta SP is always 0vu. There are variations on the Digital side from -12 to -20 depending on the format and production house, but it is always 0vu on analog.

  Here is what I am doing for Betacam SP.
  1KHz with Bars peaking at -9dBfs
  Programm peaking at -0.1dBfs
  Master out PPro slider at -9dBfs
  This also means that from your editing app kHz tone goes out at -18dB
  and programm goes at -9dB

  In this situation readings on Betacam SP VU are: 1kHz is at 0VU and programm on peaks goes “little” over 3dB VU.
  This is also VU readings from tapes that I receive from international brodcasters on Betacam SP.

  All this goes out from Decklink Extreme. PAL, Europe.

  If your VU readings on UVW are not like this, then you have to calibrate your input on UVW machine to match those readings.
  After all thats what this is all about.
